Website accessibility audit against WCAG

We are looking for a specialist to test the accessibility of our website against the WCAG standard. Our site has grown over several years, and we now realise that a portion of our visitors cannot use it fully: people with low vision, those who rely on the keyboard alone, and users of screen reading software. We need an honest and thorough review across three areas. First, keyboard navigation: whether every control is reachable with the Tab key, whether the focus indicator is clearly visible, whether there are any focus traps, whether the skip-to-content link works, and whether the tab order is logical. Second, contrast: text, buttons, links and field labels must be comfortable to read, and error states must never be conveyed by colour alone. Third, screen reader compatibility: meaningful headings, proper field labels, alternative text for images, and correct announcement of dynamic changes and modal dialogs. As a deliverable we expect a detailed report: a list of failures mapped to conformance level A, AA or AAA, screenshots, concrete recommendations for each issue, and priorities our team can act on. It is important that the fixes can be handed to developers without further explanation. Experience with real projects and an understanding of genuine usage scenarios are essential.
